DIY Astrobox, no local wifi on 1st boot

I just flashed 2 SD cards with Astrobox. I have a raspberry PI 3 B and 3 B+. I have used both SD cards and both PIs and I can’t get it to create a local astro.xxxx wifi so I can start the setup. Does anyone have any suggestions?

I had good luck for many years Octoprint, but had connectivity issues so I decided to try Astrobox. This makes me think I might have a hardware issue in general.
